Ukraine Air Alert App Hacked: False Radiation Warning in Kyiv
Ukraine's Air Force says its air-raid alert app was hacked and sent false radiation and chemical attack warnings for Kyiv. Officials blame Russia; no one has claimed responsibility.
Ukraine’s official air-raid alert app was likely hacked on Sunday and pushed out false emergency warnings telling Kyiv residents a radiation hazard and a chemical attack were underway, according to Ukraine’s Air Force. The Air Force said there was no radiation threat and urged people to stay calm and follow official updates. Ukraine’s Center for Strategic Communications blamed Russia, though no group has publicly claimed responsibility.
What happened
The false alerts appeared on the app and on the public online air alert map, which showed Kyiv and other regions as facing a nuclear alert. One message read: “There is a radiation hazard alert in Kyiv. Do not go outside!” A second warned of a chemical attack and gave the same instruction to stay indoors. The app also carried false warnings about Russia’s hypersonic Oreshnik missile and alleged street fighting in Kyiv.
Street loudspeakers also broadcast a recorded message telling people to take precautions, according to the source report.
The Air Force posted on Telegram that the app appeared to have been “subjected to enemy influence” and repeated that there was no radiation threat.
Separately, Russia’s Emergencies Ministry said early Monday that its own mobile app had been hit by a “massive cyberattack” that let attackers send false information to the public. The ministry announced this on Telegram. There is no confirmed link between the two incidents in the source material.
Why it matters
Air-raid alerts are a core safety tool in Ukraine: they tell people when to move to shelter. A fake alert that tells residents to stay inside during a real strike, or that spreads panic about radiation, can undermine trust in the system exactly when it is needed. This suggests the value of such an attack is psychological as much as technical — sowing confusion and doubt about official channels.
The timing is notable. The source report notes the false alerts came as Russia launched a ballistic missile attack on Kyiv, hours after President Volodymyr Zelenskyy warned of a major strike. That does not prove coordination, but it is likely to sharpen official suspicion.
Attribution remains unconfirmed. Ukraine’s strategic communications center pointed at Russia, but no evidence was published in the source, and no group claimed the operation.

What this means for you
- If you are in Ukraine and use the alert app, treat any single alert with caution until it is confirmed by the Air Force’s official Telegram channel, which the Air Force itself directed people to follow.
- Do not act on radiation or chemical attack warnings that appear only in the app and are not echoed by official channels.
- Expect the possibility of further spoofed messages; the source does not say whether the vulnerability has been fixed.
- For readers outside Ukraine, the incident is a reminder that public emergency apps can be impersonated, so verify unusual alerts against a second official source.
Frequently asked questions
Was there a radiation leak in Kyiv?
No. Ukraine’s Air Force said there was no radiation threat and that the alert was the result of the app being hacked.
Who hacked Ukraine’s air alert app?
Ukraine’s Center for Strategic Communications blamed Russia. No group has publicly claimed responsibility, and the source report does not include technical evidence of who was behind it.
Is the app still compromised?
